4) The DBASE_FLASH is copied into DBASE_RAM. All the parameters and
respective records have the user’s customization.
5) The attribute MEMO of each parameter is checked and if it is equal to RUN the
parameter’s value is copied from DBASE_EEPROM to DBASE_RAM.
2.1.4 Parameters and variables
The configurations parameters of the DGF can be divided in two main categories:
-
Predefined
- General
The two categories are necessary because the DGF, unlike the Drive, is a programmable
device. This means that a user, during the development of a regulation program, could
need to use parameters to configure the program developed.
The predefined parameters are used to configure the basic functions of the DGF
firmware. Their behavior is totally fixed during the development of the basic software,
as in the Drive parameters.
The general parameters are defined by the firmware but their behavior is not defined.
The behavior of these general parameters is determined by the user , who develops the
application. This means that the user can develop some regulations that can be configured
later, for instance through the keypad of the drive. General parameters have the same
rules as predefined ones.
Win+ VERSION 1:
The general parameters are effectively composed of two arrays of variables :
-FVAR is an array composed of 50 variables of floating-point type
-IVAR is an array composed of 50 variables of integer type
Win+ VERSION 2:
The general parameters are effectively composed of three arrays of variables :
-FVAR is an array composed of 200 variables of floating-point type
-IVAR is an array composed of 200 variables of integer type
-NUM is an array composed of 100 variables of configured type
All these variables can be used for any reason inside the program developed by the
user. These variables are totally at the user’s disposal. This doesn’t mean that the DGF
firmware will not modify these variables, such as:
- Initialization
- Management of the access to the variable from the external environment
- Storage
